REENFORCING CONCRETE WALLS .AND THELIKE.

Application filed February To all whom t may concer/a:

Be it known that I, HARVEY HANNA, a citizen of the United States of America, residing at Detroit in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Reenforcing Concrete Valls and the like, of which the following is a specification, reference being had therein to the accompanying drawings.

TheV invention relates to reenforcing concrete walls and the like, and particularly to means for positioning and supporting the several types of reenforcing material customarily imbedded in concrete walls and other similar partitions.

.An object of my invention is to provide a simple and efficient means of this character which may be readily assembled, and which furthermore may be attached with facility to any of the various structural frame elements of the walls of building.

Other objects of the invention as well as one embodiment of the same will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawing wherein:

Figure 1 is a fragmentary front elevation of a section of struc-tural elements of a wall or the like showing the application of this invention `Figure 2 is an enlarged sectional view taken substantially on the planeindicated by line 2 2 in Figure l;

Figure 3 is a fragmentary perspective view partly in section showing the details of construction; and

Figure 4 is a perspective view of the attaching clip.

Referring now particularly to the drawings wherein like characters indicatel like parts, it will be noted there is illustrated a pair of uprights 10 which may be two of the uprights of the structural framework of the building or of the wall, while the reference character 11 indicatesl a pair of horizontal structural frame members here shown in the form of angle irons. Y

In constructing walls of concrete or the like there is imbedded therein reenforcing material usually of wire fabric or expanded metal, and in the drawings herewith this reenforcing material is shown as wire fabric 12. It will be obvious, however, as this description proceeds, that any of the known or 1e, 1925. serial no. 9,636.

a nut 16 threaded onto the bolt and engaging the outer washers 15 for securing the bolt 14 in place. j

After a plurality of bolts or projections 14 have been arranged along a frame member 12 substantially as above described, a bar 17 is put in position preferably resting on the bolts 14 as illustrated. These rods 17 constitute the members to which the reenforcing material is adapted to be attached, this connection being preferably although not necessarily eected by tying the reen-l forcing material 12 to rods 17 at a plurality of points as indicated at 18 in Figure 1.

For securing the rod 17 to the projections 14 there is provided a plurality of subs-tantially double' U-shaped clips 19, which may be conveniently formed of Wire, bent sub stantially as shown in Figure 4, which clips engage the bolts or projections 14 in the manner illustrated, and embrace the rods 1T. The nut 16 on each bolt 14 as well as the adjoining washers 15 constitute spacing elements and the nut is abutted by the clip 19. The clip 19 is locked on the bolt 14 by means of a nut 20, a washer' 21; being prefer ably interposed between the clip 19 and the nut 20. Obviously the rods 17 may be posit-ioned below the projections 14 when desirable by merely reversing the position of the clips 19.

The number and spacing of the bolts or projections 14, as well as the gauge of the rods 17 will depend upon the dimensions of the wall and the weight of the reenforcing material, and the spacing as well as the dimensions of these elements may consequently be varied as found desirable or necessary.

It will be noted that the double. U-shaped clips are looped over the rods 17 and also engage under the respective bolts 14, and when pressure is exerted upon these clips 19 by means of the nuts 20 a positive locking engagement of the parts is accomplished. Not-withstanding this it will be readily apparent that the parts may be easily assembled or disengaged as desired.

With a supporting and spacing means as hereinbefore described, the reenforcing means for concrete walls or the like may be properly supported at as many transverse and vertical points as desirable, and may also be properly spaced with reference to the transverse thickness of the wall by varying the thickness or number 'of the washers so that the reenforcing material will be arrai'igedsubstantially in the desired verticalr plane of the completed wall. The herein described construction also provides a mechanically satisfactory and permanent support for this reenforcing material.

lVhile an'embodiment of the invention has been illustrated and described in some detail, it will be immediately apparent that various modifications may be resorted to without departing from the spirit and scope of this invention, and to this end reservation is made to make such changes as may come within the purview of the accompanying claims.-

What I claim as my invention is: l. The combination with a structural member of a wall, of means for supporting thereenforcing material of the wall comprising a supporting member, fastening means engaging said structural member and disengageable means for securing said supporting member to said fastening means.

2.*Spacing and supporting means for the reenforcing means '0f a wall or the like, comprising vmembers upon which the reenforcing means is supported, projections secured to the structural elements of the wall or the like` and means forl connecting said members to 'said projections.

3. Spacing and 'supporting means for the reenforcing means of a wall or the like, comprising members to which the reenforcing means is connected, projections secured to the structural elements of the wall or the like, and clips for connecting said members to said projections.

4. Spacing and supporting means for the reenforcng means of a wall or the like, comprising members upon which the re'enforcing means is supported, projections secured to the structural elements of the wall or the like, and detachable clips for securing said members to said projections.

5. A support for the reenforcing material of walls and the like comprising rods to which the reenforcing` material is attached, spacing means secured to the structural elements of the wall and U-shaped clips for securing said rods to said spacing means.

6. The combination with the structural framework of a concrete wall or t-he like, of supporting means for the reenforcing material of said wall comprising rods for supporting the reenforcing material, projections secured to said framework, and clips engaging said projections and rod for securing said parts together. e

7. The combination with the structural framework kof a concrete wall or the like, of supporting means -for the. reenforcing material of said wall comprising rods for supporting the reenforcing material, projections secured to said framework, and a clip connected to veach projection and embracing said rod for securing said parts together.

8. The combination with the structural frame of a concrete wall or the like, of supporting means for the reenforcing material of the wall comprising horizontally extentiing rods for supporting the re'enforcing material, bolts secured to said frame at spaced intervals, and clips engaging said bolts and rods for securing said parts together. j

9. The combination with the structural frame of a concrete wall or the like, of supporting means for the reenforcing material of the wall comprising horizontally extending rods for supporting the reenforcing material, bolts secured to said frame at spaced intervals, spacing members on said bolts and clips embracing said bolts and rods for securing said rods inplace, spaced from said structural frame.

l0. The combination with the structural frame of a concrete wall or the like, of supporting means for the reenforcing material of the wall comprising horizontally extending rods for 'supporting the reenforcing material, bolts secured to said frame at spaced intervals, and double U-shaped clips embracing said bolts and rod for securing said rod to said bolts spaced from said structural frame.

11. The combination with the structural frame of a concrete wall or the like, of supporting means for the reenforcing` material ofthe wall comprising horizontally extending rods for supporting the reenforcing material, bolts secured to Said frame at spaced intervals and a clip connected to each bolt and embracing said rod, and a nut on said bolt for securing said clip inengaging position.

In testimony whereof l aiiix my signature.
